I would say @Vantha's PR for campaign UI would have to be merged so we could have some form of narrative, then if the mod author is willing this may be a good first campaign to work on polishing.
I've had this error when I've launched 0 A.D. with a flatpak on fedora @Perzival12 what distro are you using and what graphic card do you have and how is the drivers installer?
I think the concepts are pretty cool.
My only suggestion is don't lock down how the campaign's narration works, it would be kind of cool to have room to have the campaign designers to have some artistic difference.
I've been having a problem with gitea not forking the 0 A.D. repo for me. I've tried forking on different systems, web browsers, and networks, and consistently I'm getting a 502 proxy error. Is anyone else getting the problem?
